	'''OR1N2''' is a gene that encodes the olfactory receptor, family 1, subfamily N, member 2 protein in humans. The [[olfactory receptor]] proteins are members of a large family of G-protein coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome.

	== ~~Structure~~ ==		==Function==
			Olfactory receptors, such as OR1N2, interact with odorant molecules in the [[olfactory epithelium]] to initiate a neuronal response that results in the perception of a smell. The olfactory receptor proteins are characterized by a 7-transmembrane domain structure, which is a common feature of many neurotransmitter and hormone receptors.

The OR1N2 gene is one of the many olfactory receptor genes located on [[chromosome 9]]. These genes are responsible for the recognition and G protein-mediated transduction of odorant signals.

			While the primary function of OR1N2 is related to the sense of smell, variations in olfactory receptor genes can influence individual differences in odor perception. However, specific clinical conditions directly associated with OR1N2 have not been extensively documented.

'''OR1N2''' is a gene that encodes the olfactory receptor, family 1, subfamily N, member 2 protein in humans. The [[olfactory receptor]] proteins are members of a large family of G-protein coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome.

== Function ==

The OR1N2 gene is part of the [[olfactory receptor]] gene family, which is the largest gene family in the human genome. The proteins encoded by these genes are responsible for the recognition and transduction of odorant signals, which are mediated by G proteins. This gene family is highly polymorphic and diverse, with each gene encoding a unique receptor that can recognize a specific odorant molecule.

While the specific clinical significance of OR1N2 is not yet fully understood, the olfactory receptor gene family as a whole has been implicated in a variety of diseases, including [[anosmia]] (loss of the sense of smell), and [[olfactory neuroblastoma]] (a rare type of cancer that starts in the olfactory nerve).
